"If you borrow money from a person you can liquidate it if you repay it, but it will not work if you try to recover the sleeping debt.While there is some effect on sleeping for a long time when you can take a sleep, it will not be an amendment." Dr. Kathy Goldstein, specializing in neurology at the University of Michigan Sleep Disorders Center, says. Research results published in science journal Nature backed Dr. Goldstein's claim that according to the study, enough sleep for four days is necessary to make up for an hour's sleep debt, It seems that you can not liquidate sleep debt just by sleeping for a while.

The human body clock begins secretion of melatonin which is a hormone that urges sleep around 21 o'clock. And its secretion level will remain high until it descends the next morning. Even though you can not sleep a bit by watching the PC or smartphone screen during the night, if you maintain a stable sleeping habit it will not cause madness in the body clock. However, as soon as the sleeping habit becomes irregular even a little, the body clock will be affected. As you stay up late it will gradually become sleepy even at night, but that does not mean you did not need to go to sleep. "If you feel it is hard to fall asleep, it is a sign that the biological clock has changed," Dr. Goldstein says.

According to Dr. Goldstein, it is said that taking a nap is more effective than sleeping if it gets lack of sleep once. The National Sleep Foundation, a national nonprofit organization on sleep research in the U.S., has found that refreshing effects are recognized even in a nap of only 20 minutes. In addition, it is expected that you can improve the quality of sleeping on weekdays by keeping regular sleep on holidays.
